You use -99 in your input file to indicate end of line, but you seem to expect -999 in your program . . . .

x = bool (x||y) ;
That is C++ only. The C way looks like this.

In order to use the ifstream fin variable that you declare inside the switch statement, you need to declare it outside the switch statement. For example:
